[FEAT] Disable fetching for specific package manager

[carterprince]

Current state:

Currently, fastfetch shows several different package managers, but I only want to fetch the package count from rpm for performance reasons.

Why the change is sensible:

The user should be able to configure which package managers get queried, in case it takes too long to fetch all packages with a bunch of different managers.

If this is already supported my apologies, I skimmed through the configuration options and didn't see anything like this.

Thanks.

You may test it with fastfetch --packages-disabled whatever:package:managers

Works! Thanks.
